摘要
为解决电解水制氢与燃料电池发电过程中的散热问题,依据电解槽与燃料电池的水冷式散热原理,设计了独立光氢燃料电池热电联供系统。以此为模型基础,制定了控制策略综合协调各模块的启停顺序及出力大小,解决了电解槽低功率运行区间的低效率问题。以综合成本最优为目标函数建立容量配置模型,采用改进粒子群算法得到系统容量最优配置方案。仿真结果表明:所提配置方案与传统配置方案相比,综合成本可降低2.2%,同时能满足储氢罐和储热罐在一个运行周期内始末状态相同,系统的长期稳定供能效果较优,可为目前独立光氢燃料电池热电联供系统容量配置提供一定的参考价值。
In order to solve the problem of heat dissipation in the process of producing hydrogen from electrolytic water and generating electricity from fuel cells,an independent photohydrogen fuel cell thermoelectric combined supply system was designed according to the principle of water cooling heat dissipation between electrolytic cell and fuel cell.Based on this model,a control strategy was formulated to coordinate the output order and size of each module,which solved the inefficiency of electrolytic cell in low power operation zone.The capacity allocation model was established with the objective function of optimal comprehensive cost,and the optimal capacity allocation result of the system was obtained by using the particle swarm algorithm.The simulation results show that the overall cost of the configuration scheme proposed can be reduced by 2.2%compared with the traditional configuration scheme,and it can meet the same starting and ending states of the hydrogen storage tank and the heat storage tank during the operation cycle.The long-term energy supply effect of the system is excellent,which can provide a reference value for the capacity configuration of the current stand-alone photohydrogen fuel cell cogeneration system.
